Abstract

The composition of the invented nano composite latex paint comprises (wt%) 0.3-1% of moistening dipersant, 2-70% of nano pulp, 1-4% of film-forming adjuvant, 0.5-2% of anti-sedimentation agent, 0.8-15% of antifreeze agent, 0.5-3% of defoaming agent, 5-30% of pigment, 0-30% of filling material, 10-45% of emulsion, 0.2-2% of thickening agent, 0.2-2% of leveling agent, 0-2% of pH regulating agent, 0-2% of microbiocide and 2-35% of water. Its preparation method includes two steps: firstly, preparing dispersion stable nano material pulp, then adding said nano material pulp into the latex component according to a certain process so as to obtain the invented high-performance product.

Description

technical field [0001] The invention relates to paint technology, in particular to a nanocomposite latex paint and a preparation method thereof. Background technique [0002] Latex paint is a kind of water-based paint, which contains very low organic volatile matter, meets the requirements of environmental protection, and belongs to "green paint". It has been greatly developed since the latex paint was produced, and people continue to find ways to improve the performance of latex paint from different aspects. The emergence of nanomaterials has brought opportunities for the improvement of the performance of latex paints. For example, Chinese invention patent CN1277234A discloses a kind of architectural paint containing 0.5-1.5% silicon-based oxide. Improve the suspension, bonding strength, aging resistance and pollution resistance of the coating. Chinese invention patent CN1287145A reports a nano-paint for exterior walls prepared with nano-silicon oxides, nano-titanium oxi...
